42% of dengue mosquito breeding sites are in reservoirs of water intended for human consumption — Portuguese (Brazil)

The Rapid Index Survey of Aedes aegypti (LIRAa), carried out by the Ministry of Health, indicated that 42% of dengue mosquito breeding sites are in water reservoirs intended for human consumption. . These figures reinforce the importance of the participation of the population in the fight against the proliferation of Aedes aegypti, the mosquito being more and more accustomed to the domestic environment.

The survey also highlighted that mobile, fixed and natural depots appear as the second breeding ground for mosquitoes, with 32%, while garbage depots have an incidence of 25%.

With high temperatures and rainy seasons, the number of breeding sites is expected to increase. For this reason, society must commit to eliminating breeding sites and avoiding standing water. And the measures are simple and can be implemented on a daily basis. Specialists from the Ministry of Health suggest that the population carry out a home inspection at least once a week.

The Pasta reinforces that to effectively control the proliferation of the mosquito, it is necessary to take at least 10 minutes to check the roof, the clogged gutters, the swimming pool, the bottles, the tires and other objects which could become breeding grounds for the mosquito. transmitter. Even in places that need water storage, it is important not to leave the tanks uncovered.

The main measures to eliminate the formation of breeding sites are:

  • Wash barrels, gallons or water tanks with soap and water and keep them tightly closed;
  • Keep water tanks tightly closed;
  • Clean and remove leaves from gutters, always leaving them clean;
  • Remove accumulated water from the slabs;
  • Unclog drains and keep them closed or with grates;
  • Put sand or putty on the broken glass walls;
  • Wash plants that accumulate water, such as bromeliads, twice a week;
  • Fill the hollows of trees and bamboos with sawdust, cement or sand;
  • Avoid using dishes on the plants, if you want to keep them, put sand to the edge of the dishes of plants or tree fern;
  • Treat the pool water with chlorine and clean it once a week;
  • Remove the water and wash the outer drawer of the refrigerator with soap;
  • Thoroughly wash the mineral water bottle holder after each change;
  • Wash animal bowls with a sponge or loofah, soap and running water, change them once a week;
  • Keep fish tanks clean and covered or screened;
  • Keep toilets clean and lids tightly closed;
  • Store empty bottles and buckets upside down;
  • Throw away objects that can accumulate water, such as: cans, bottle caps, eggshells, disposable cups;
  • Always keep the trash well capped and the plastic bags tightly closed;
  • Drill holes in the bottom of the external bins;
  • Throw away or send old tires for recycling or puncture them and store them in a dry and covered place.

In case of symptoms such as fever, headache and body aches, the patient is recommended to go to the health center closest to his home for treatment.

Sustainability

To ensure protection against the mosquito vector of arboviruses, the Ministry of Health sends biolarvicide to states and municipalities, depending on the local epidemiological situation and demand. The product represents an effective alternative in the control of mosquito larvae, as it can be added wherever water collects and has the potential to be a breeding ground for insects.

The new technology guarantees a lower environmental impact, since it is a biological product with a low impact on human health. The treatment of certain breeding sites with the biolarvicide must be considered complementary and target deposits that cannot be eliminated or managed in any other way, mechanical control always being the first alternative.

The great advantage, compared to traditional insecticides, is that the biological product only kills mosquito larvae, without affecting people or pets, including fish, birds and other beneficial insects. It also does not affect the environment, since it is neither cumulative nor polluting.
